ScholarBank@NUS Repository. | Abstract: | The blue-light-emitting crosslinkable hyperbranched polyfluorene P2 with higher content of branched unit were synthesized by the palladium-catalyzed Suzuki coupling reaction. The molecular weight and thermal behavior was analysized by GPC, DSC and TG By contrast with the lower branched unit content hyperbranched polyfluorene P1 and linear polyfluorene P0, the photoluminescence (PL) spectra of P2 shows excellent stability even annealing in air at 200°C after 3 hours after crosslink. The stabilized hyperbranched polyfluorene can be used in multilayer and multicolor PLED. | Source Title: | Journal of Optoelectronics and Advanced Materials | URI: | http://scholarbank.nus.edu.sg/handle/10635/75186 | ISSN: | 14544164 |
